Amateur Radio Propagation Analysis with Erlang/OTP and Riak


By Erlang Central | Published: March 18, 2013



Automated signal analysis in multiple reception locations enables a large-scale data analysis opportunity for radio propagation. The accumulated datasets result in millions of reception reports, which is suitable for applying “big data” solutions. In this presentation, Kenji describes a problem solution approach with Erlang/OTP and Riak to store and analyze the reception reports from two different amateur radio shortwave reception networks called reversebeacon.net and WSPRnet, and shows how to achieve a good computational performance.

Talk objectives: Showing how a KVS-based approach is different from the traditional SQL-based database approach, and how Erlang/OTP and Riak can effectively utilize the distributed and multi-core system environment.
Target audience: Entry users of database applications on Erlang/OTP, including not only those of Riak, but also of the other “NoSQL” database implementations.
